Analysis of Temporal and Spatial Evolution Characteristics of Rainfall in Dongguan in the Past 30 Years by WANG Qiuliang, SUN Xiang, GAN Dufen, MEI Xinpei, CHENG Jie, ZAN Xiongfeng

“…Dongguan is an important city in the Guangdong-Hong Kong-Macao Greater Bay Area,which is a major contributor to the economic development of this area.However,its urban planning,rational allocation of water resources,flood prevention and disaster reduction are severely affected by torrential rain and floods,and thus its high-quality economic development is seriously hindered.Therefore,by using the 32-year daily rainfall data of 30 hydrological stations in Dongguan,this paper adopts methods such as GIS,the Mann-Kendall test,moving average,and cumulative anomaly to discuss the temporal and spatial distribution of rainfall in Dongguan.The results reveal that in the past 32 years,the temporal and spatial distribution of annual rainfall has gradually increased from west to east with a significant rising trend over time.During the flood season,the rainfall increases sequentially from west to east and gradually decreases from the central part to west,and from the central part to east,it drops before it rises.Rainfall in the flood season accounts for about 60%~95% of the annual total.The rainfall in the non-flood season is prominent in the central part,with great differences between east and west,namely that the rainfall in the central part tends to decrease gradually to both sides,and the southwestern part registers the smallest.The center of the maximum rainfall in the four seasons moves from the central part to the northeast,east,and central,and the southwest still records the minimum rainfall.The monthly average rainfall generally shows an increasing trend from west to east:Many years of data indicates that the average rainfall in June is the largest,accounting for 18.58% of the rainfall all year,while December sees the smallest,accounting for 1.88% of the yearly total.The research results can provide reference and support for the later development of Dongguan.…”

Characteristics of Runoff Variation of Heishui River Basin in the Upper Reach of Minjiang River in Changing Environment by WANG Ning, WANG Wensheng, YU Siyi

“…This paper systematically analyzed the variation characteristics of runoff in the Heishui River Basin,the first tributary on the right bank upstream of Minjiang River,in a changing environment.The variation characteristics of runoff series were studied by using an improved heuristic segmentation algorithm,Mann-Kendall trend test,R/S analysis and wavelet analysis with the runoff data of Shaba hydrological station from 1960 to 2015.The results show the followings:① The abrupt change of annual runoff occurred in 1995.② The annual runoff showed a significant decrease trend with a decreasing rate of 0.32 m³/(s·a) in the past 56 years and may keep the decrease trend in the future.During 1960—1995,the annual runoff showed an insignificant decrease trend with a decreasing rate of 0.12 m³/(s·a),and the period of 1996—2015 witnessed an insignificant increase trend with an increasing rate of 0.80 m³/(s·a).③ Under the influence of environmental changes,the average annual runoff before the change point was larger than that after the point,whereas the inter-annual variation was smaller before the abrupt change.The intra-annual distribution form showed a double-peak curve before 1995 and a single-peak curve after 1995.The intra-annual variation range of runoff was significantly different before and after the change point,which could reduce flood control pressure in the basin but was not conducive to the utilization of water resources in non-flood seasons.④Annual runoff had multi-time-scale variation characteristics.During 1960—2015,the annual runoff had noticeable periods of 6 years,16 years and 28 years.Periods of 7 years and 16 years were found for 1960—1995 and 2 years and 5 years for 1996—2015.…”

Study on Spatial-temporal Characteristics of Drought Duration and Intensity in Leizhou Peninsula in Recent 50 Years by DU Xiaoxia, TU Xinjun, XIE Yuting, WANG Tian

“…In the background of global warming,drought disasters occur frequently,bringing serious impacts on the natural ecosystem,human production and life and social & economic development.Therefore,it is of great significance to analyze and assess regional drought characteristics and study local drought mitigation and disaster reduction decisions and climate change.Based on the meteorological and hydrological data of 12 sites in Leizhou Peninsula from 1970 to 2019,this paper identifies and evaluates the drought events via standardised precipitation-evapotranspiration index (SPEI) and run theory,and analyzes the temporal and spatial variation characteristics of drought duration and intensity in Leizhou Peninsula in recent 50 years combined with curve fitting method,inverse distance weighted spatial interpolation,etc.The results show that:①The monthly SPEI index of the Leizhou Peninsula in recent 50 years showed a decreasing trend in fluctuation.On the time scale of the recent 50 years,it fluctuated with a period of about 10 years,which is related to the influence of ENSO.The SPEI is relatively high in cold event years,on the contrary,in warm event years,the SPEI is low and the drought is serious.②The greater the intensity of drought disaster in Leizhou Peninsula,the smaller the probability.③Due to regional difference,the spatial distribution of drought frequency,intensity and duration showed a gradually increase trend from the northeast to the southwest.④The regional difference of the occurrence frequency of drought of different grades showed that the frequency of moderate drought and above in the central and southern and northeastern regions of Leizhou Peninsula was higher than that in the central and northern regions.In addition,the drought in the southern part of Leizhou and Xuwen County was severe.⑤Droughts occur frequently in spring and winter.In spring and summer,the drought in the northeast and central-south part of the Leizhou Peninsula was more severe,the drought in autumn was more serious in the central-north part of the peninsula,and the drought in winter seriously affected the central-south part of the peninsula.…”
